Hi John,
Thanks for your patience.
1. We have an issue in this, when the multi selection is done and then by right clicking on the selected are it deselects. For this we request you to post an Incident in the Direct-Trac, we will surly update you with the solution.
2. To check whether the right click is done in the data cell or in the header cell, we have to check with the CellType. Through that the action can be performed.
Please refer the code snippet and sample from the following.
[Code Snippet]
RowColumnIndex rci = dataGrid.Model.Grid.PointToCellRowColumnIndex(e);
if (!rci.IsEmpty && this.dataGrid.Model[rci.RowIndex,rci.ColumnIndex].CellType=="TextBox")
{
}
